The man behind an alleged “Ponzi-type” scheme accused of bilking Warren Buffett’s Berkshire Hathaway out of $340 million was a NASCAR sponsor who partied with Pitbull and owned more than 150 cars, according to court documents.

Jeff Carpoff, the CEO of the now defunct energy company DC Solar, lived a lavish lifestyle before the FBI raided his and his wife Paulette’s Martinez, Calif., home and DC Solar’s offices in December, court papers show.

Among the treasures now in the feds’ possession include a car collection totalling at least 157 cars, including three Bentleys, a 1926 Ford Model T, 17 Dodge Rams, and 15 Chevy Camaros.

Also seized were season tickets for the yet-to-be-formed Las Vegas Raiders NFL team worth $782,949; more than $50 million in bank accounts, over 30 properties scattered throughout California and Nevada, and a stash of jewelry, including a “three prong diamond necklace” and a Ballon Bleu de Cartier watch worth more than $6,000, court papers show.

Prior to the raid, the Carpoffs were a big name in their town, about an hour and a half northeast of San Francisco, according to reports. They were owners of the Martinez Clippers, a professional California baseball team that wasn’t associated with Major League Baseball, and DC Solar was the sponsor of Kyle Larson’s Energy NASCAR Cup race team, which is owned by Chip Ganassi Racing.

And as recently as December, DC Solar even hired “Fireball” singer Pitbull to perform at the company’s annual Christmas party, according to Carpoff’s Twitter account. And he and his wife were sponsors of the town’s annual Martinez Downtown Holiday on Ice, an ice skating rink, according to the Martinez Gazette.

On Wednesday, the Oracle of Omaha’s $738 billion investment fund revealed that it took a $377 million charge tied to $340 million in investments it gave to DC Solar, the solar power generation company that Carpoff ran.

Berkshire said it had invested the money in various tax equity investment funds starting in 2015 — before learning that the feds had alleged “fraudulent income conduct” tied to the company.

“We now believe that it is more likely than not that the income tax benefits that we recognized are not valid,” Berkshire said.

It’s unclear what — if anything — the Carpoffs did wrong. Neither the family nor their company has been indicted. The Carpoffs, as well as a lawyer representing them, didn’t return requests for comment.

But an FBI agent said DC Solar appeared to have operated in a way that reflected “evidence of a Ponzi-type investment fraud scheme,” according to a Feb. 8 affidavit related to bankruptcy proceedings.

The Securities and Exchange Commission also accused DC Solar’s owners by name of engaging in a Ponzi scheme, according to a separate court filing.

According to the local Martinez paper, Carpoff still owes the city $30,000 for use of a field where his baseball team played. Efforts to find a new owner for the team fell through in March, the paper said.
